TUPIZA, P.; PAVON, W.  e  JARAMILLO, M.. Total Harmonic Distortion Reduction Through Photovoltaic Generation and Unified Active Power Filter (UAPF). Revista Técnica energía [online]. 2022, vol.19, n.1, pp.92-99. ISSN 2602-8492.  https://doi.org/10.37116/revistaenergia.v19.n1.2022.522.

This paper proposes a unified active power filter (UAPF), which control the current Total Harmonic Distortion (THD) in low voltage distribution networks. The UAPF strategy implements photovoltaic (PV) generation as its source and uses a boost power converter.

The IEEE 13-bar system is the test-bench, and a non-linear load is in the 7th busbar. Thus, the results are based on the voltage, current and THD behavior in the system. The current (THDi) and voltage (THDv) harmonics reduces significatively. Where the 7th busbar THDi initially has a 13.5 percent, and after the implementation it went 6 percent, while the THDv started from 14 to 3 percent. Those resulted values are within the allowed limits in IEEE 1159 standards and resolution No. ARCERNNR -017/2020.
